I; This invention relates to shuttles, especially to those used in weaving woolen yarn or other similar yarn which carries along a certain amount of short fibre or fuzz which may get into the shuttle eye and clog it and'for any other shuttles .where a gentle tension or holding back qnthe yarn isdesirable. l v V In. the past, and in addition; to the various typesof friction pads in the shuttle eye and fur 3 which engages the yarn mass on the bobbin, bristle brushes extending into the bobbin chamber imposition to intercept the thread have been extensively used. v 1 V l The usual method of positioning these" brushes is i to bore a hole through the side of the shuttle leading into the bobbin chamber and then force easily be removed, as by the use of a screw driver and a wrench; for replacing the worn bristles orto be itself replaced. t

In the drawing,

Fig. 1 is a plan view of the eye end of a shuttle withmy deviceinplacegjq t x v i y Fig. 2 is an elevation from the side of the shuttle eye of the same-shuttle shown in Fig. 1, part oi the wall being broken-away to show a t brushin the'opposite interior wall.

abunch of bristles into thishole either smearing-the inside of the hole'or the outside of the bristleswith adhesive so thatthey stayin posi tion; 1 v u When thebristles wear down and it is necessary to replace them, ,it is a diificult task to clear the hole ofnbristles and adhesive and to do agood job, thes'huttle must be taken out of service into a properly equipped shop.

My device is a bristle brush for shuttles and comprises a bunch of bristles and a holder therefor, the holder including a receiving member which when attached in position in the shuttle can remain in that. position to receive a brush holding member which can be removed and re:

placed or both can be removedtoge-ther and both can then be replaced. The brush holding member is preferably of a character which requires no; adhesive to hold the bristles in place. n

;...Mypreferred way of accomplishing thispurpose is to have the, two members so arranged that when the brush holdingmember is screwed into thereceiving member, the bent part or the ends of the bristles which project through the bristle holding. member willspread out or mushroom and be firmly squeezed in place between thetwo members.

Fig 5 1s a sectional :viewethrough part of a shuttle "wall and through the receiving member, {the brush holding member being shown in ele- Eig.;6 is an isometric view showing a brush p itioni J Preferablythere is a hole through the bristle holding member at an angle with its'axis and preferably a'loop of a bunch of bristles; is pulled throughthe hole by a thread and the thread is thenstitched through and through the loop or tied around it. H v l v i The holding and the receiving members may be made in various ways and the receiving mem-.

ber: may be attached to the shuttle in various ways. It may be easily removable or permanently fixed in position but the brush holdingmember isso attached that it will not be loosened by the holder removed from the receiving member with the bend of the bristles flattened out or mushrjoomed as they; are when the brush holder is in l 'ig. flisa similar view to Fig. 5 of a modified construction of receiving member and brush preferably double the length required, and are f bent at I a shown in 3. D represents the thread,- A v Through a side wall ofithe shuttle and extending into the bobbin chamber 40 are one or more holes such as B. each-of which at the outside is counter-boredto form a concentric annular recess 5 and to form an inwardly extending ane nular rib l6.

jl'he bristle brush unitrH isformed of -several" 7 parts andincludesespecially a receiving,member F with a headi 5"Whi0hpreferably fits snugly insideithe recess 5 and ashank I2 which fits fairly close in the hole 6. As shown this shank l2,isthreadedontheoutside l8 and in it is the axially positioned deadendhole 14 with interior threads 3. W is a washen'of which one or more a v s "2,371,701 is shaking oft-the loom but at the same time can 43 near the front of the i over it as shown in Figs. 1 and 2. H The brush holdin member M has a head I which preferably is of hexagonal or other si-milar shape so that a wrench can easily lg-rasp it and a neck 2 through both of which extends a bristle hole 4 which preferably isbdred -at an angle and which, on the inside, is preferably '20 may be used, which fits over the shank l2 against theinside er the sideof. the shuttle in the bobbin chamber between it and a holding nut C which is provided with interior threads 38 which .en-

gage the outside threads I8 of shank [2 of member F.

There is a turning slot l 'for a screw driver in head l5.

There are preferably two or more brushes H, H,

' and the bunch Q e bristlesbf eaenl referably rakes or slopes gforiilardf towards the. eye end of the shuttle and either down under the bobbin or countersunk at 44. The neck 2 has"outside threads s adapted tc engage the inside threads 13 0f! theshank l2 of the. receiving member 1F 2 Q a :"hheneck 2 is preferably: not quite as images the depth of dead end holed-kin the shank l'2 .of

thememberF. With the above constructio there is a i nular, inwardly projecting "16 of the holder receiving-holes and-' when the nut c is screwed lit or rib I 6 goes through the side of the shuttle into the bobbin chamber. This hole [9 is formed with threads 29 which engage outside threadsil of areceiving member L which has a dead end "hole 24 with inside threads 23 to engage outside threads of the brush holding member 0.

There is a bristle hole 26 bored at an angle through this member 0 and countersunk at 45 and it also has preferably a turning slot 25. Receivin member L also is preferably provided with a turningsloti Zf:

The operation is the same as in thepther con- .gistruction. The bristles P are bent at 1 and stitched at 8 and mushroom or spreadat the end of the dead end hole 24.

in Fig. 8 is shown a modification of the construction shown in Fig. 7. As there shown, bristles Azare drawn -through tubular brush holding member R until they project from the end 39 where they maybe stitchedor twisted together or as shown, may be simply-allowed to spread out as wither w-ithouttl-ie nter'positioh of one or more washers such as W, "the recivingmember F is permanently fixed "inplace although it "can be removed by unscrewing the nut C, I

It can conveniently be pulled through by thread 8 and as the bend I projects, this thread issewedor twisted through and around it to form a :bunch which; i'sflargerfthaiithe hole' l. a

When neck 2 is-"screwed into the dead" end hole It; this part 7 "with the sewingthread a is spread out and mushrooms as shown in Figs; 5 aridG so that it cannot be pulled back This also -prevents any of the-bristles from*-being-pulled but individually by {the "thread as it runs off from y i As holed is at ah 'angleand it is desirable "that the -br ushes should rake *or slope' for'ward "at an at- 3'1' when this shell R, threaded' on the outside at 36, 'is screwed into the dead end hole 32 having inside threads '34 and bored at an angle into a receiving-member-T.

"Receiving member T has outside threads '35 which engage inside threads 3| ina hole 30 bored straight through the-shuttle wall. -In every construction, when the members or a brush are adjusted and fixed in place,'the axis of the bunch of bristles and of' the bristle hole is at an angle with the axis of the receiving member.
